A Novel Bioaugmentation Technique Effectively Increases The Skin-Associated Microbial Diversity Of Captive Eastern Hellbenders, Erin K. Kenison, Obed Hernandez-Gomez, Rod N. Williams Sep 2020

A Novel Bioaugmentation Technique Effectively Increases The Skin-Associated Microbial Diversity Of Captive Eastern Hellbenders, Erin K. Kenison, Obed Hernandez-Gomez, Rod N. Williams

Natural Sciences and Mathematics | Faculty Scholarship

Captive environments are maintained in hygienic ways that lack free-flowing microbes found in animals’ natural environments. As a result, captive animals often have depauperate host-associated microbial communities compared to conspecifics in the wild and may have increased disease susceptibility and reduced immune function. Eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) have suffered precipitous population declines over the past few decades. To bolster populations, eastern hellbenders are reared in captivity before being translocated to the wild. However, the absence of natural microbial reservoirs within the captive environment diminishes the diversity of skin-associated bacteria on hellbender skin and may negatively influence their ability to …

Lupus is a debilitating multi-organ autoimmune disease clinically typified by periods of flare and remission. Exposing lupus-prone female NZBWF1 mice to crystalline silica (cSiO2), a known human autoimmune trigger, mimics flaring by inducing interferon-related gene (IRG) expression, inflammation, ectopic lymphoid structure (ELS) development, and autoantibody production in the lung that collectively accelerate glomerulonephritis. cSiO2-triggered flaring in this model can be prevented by supplementing mouse diet with the ω-3 polyunsaturated fatty acid (PUFA) docosahexaenoic acid (DHA). A limitation of previous studies was the use of purified diet that, although optimized for rodent health, does not reflect the …


A Comparison Of Coyote Diets In Urban And Rural Habitats In The Piedmont Of South Carolina, Bethany Krug May 2020

A Comparison Of Coyote Diets In Urban And Rural Habitats In The Piedmont Of South Carolina, Bethany Krug

Graduate Theses

With increasing rates of urban expansion, interactions between humans and wildlife become inevitable. These urban environments present novel situations to native species, frequently resulting in their displacement or extirpation. However, some species, often referred to as “urban adapters”, have thrived in these landscapes. Coyotes (Canis latrans) are a prime example of a species that has adapted to exploit urban habitats. Coyotes are omnivores with food choices ranging from small/medium mammals to invertebrates depending on habitat. With their recent range expansion into the Southeast, little is known of their behavioral ecology in the region, especially details relating to their diet. Macroscopic …


Effect Of Calcium Supplement On Eyesight Of Western Tiger Salamanders, Abigail Horner, Dennis Ferraro Apr 2020

Effect Of Calcium Supplement On Eyesight Of Western Tiger Salamanders, Abigail Horner, Dennis Ferraro

UCARE Research Products

There has been some discussion in herpetoculture about adding calcium supplements to the diets of salamanders. Adding calcium supplements to a salamander’s diet has been indicated to contribute to blindness. Calcium supplements are usually given to reptiles and amphibians to prevent dietary deficiencies, particularly metabolic bone disease. The link between lack of calcium and metabolic bone disease is well established in reptiles, but is lacking significant research with regards to amphibians. Within the eye of a salamander, there are calcium channels that mediate photosynthetic rods in the absence of light. With a calcium rich diet, it is believed that these …


Impact Of Postweaning Management Strategies On Beef Carcass Characteristics And Meat Quality, Christina Elaine Bakker Jan 2020

Impact Of Postweaning Management Strategies On Beef Carcass Characteristics And Meat Quality, Christina Elaine Bakker

Electronic Theses and Dissertations

The overall objective of this dissertation was to determine the impact of selected post weaning management strategies on beef carcass characteristics and meat quality. The specific objectives were 1) determine the effect of a rumen-protected long chain fatty acids fed during finishing on live performance, serum fatty acid profile, carcass traits, and predicted carcass composition, and 2) determine effects of feeding brassica-based cover crops to cattle during backgrounding on live animal performance, carcass characteristics, tenderness, juiciness, and flavor of strip steaks, and case life of ground beef and strip steaks. Results from both objectives indicate post weaning management strategies do …


Growth Of Juvenile Red Abalone (Haliotis Rufescens) Fed Different Seaweed-Based Diets, Quinn C. Wulffson Jan 2020

Growth Of Juvenile Red Abalone (Haliotis Rufescens) Fed Different Seaweed-Based Diets, Quinn C. Wulffson

Cal Poly Humboldt theses and projects

The rise of abalone aquaculture has mitigated most of the global demand placed on wild stocks of abalone; however, the current production of abalone relies heavily on naturally harvested kelp. The continued reliance on wild kelp as a feed source further contributes to the disappearance of kelp forests throughout coastal ecosystems. This study aims to better understand how juvenile red abalone Haliotis rufescens grow and utilize nutrients from three diets: a control diet of naturally harvested bull kelp Nereocystis luetkeana, a formulated commercial diet (ABKelp®), and Pacific dulse Palmaria mollis produced using Integrated Multi-Trophic Aquaculture (IMTA). Juvenile …


Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez Jan 2020

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez

Theses and Dissertations--Forestry and Natural Resources

North American river otters (Lontra canadensis), native to every U.S. state and Canada, experienced extensive population decreases and range reduction until the mid-20th century as a result of overexploitation and habitat loss during European colonization. The last known river otter in New Mexico was killed on the Gila River in 1953, although unverified reports continued thru 2008. After a nearly 60-year absence from New Mexico, 33 adult river otters were reintroduced to the Rio Pueblo de Taos in the northern part of the state between 2008-2010; however, they were not subsequently monitored or studied. I characterized diet of …
